Abstract

Purpose: This study is intended to improve the performance of traffic signs corroded by aging, to ensure maintenance efficiency, a water-hardened coating solution was developed. Performance tests were then used to determine the optimal component scale. Method: For research purposes, the results were analyzed by conducting corrosion resistance assessment, physical properties evaluation, storage safety assessment, etc. on coating solutions of various magnifications. Results: The analysis results showed that there was little hearing in the cutting area in the liquid with added magnesium, so the method effect was excellent. And there was little blister occurrence, which was analyzed at the highest magnification. Conclusion: Enhancements to future new component scale experiments are needed for water-hardened coating solutions that have been recognized for their performance through this study.And institutional improvement efforts are needed to expand the enforcement of traffic sign maintenance using coating solutions.

연구목적: 본 연구는 건축물 및 교통 시설물 등에 사용중인 강재류가 시간에 흐름에 따라 부식이 발생됨에 따라 부식된 강재의 성능을 향상시키고 유지보수 효율성을 확보하기 위해 수분 경화형 방식 코팅액을 개발하였고, 그 성능 시험을 통해 최적의 성분 배율을 결정하도록 하였다. 연구방법: 연구를 위하여 다양한 배율의 코팅액에 대해 내식성 평가, 물리적 성질 평가, 저장안전성 평가 등을 시행하여 그 결과를 분석하였다. 연구결과: 분석결과 마그네슘을 추가로 첨가한 액체에서 컷팅 부위에 발청이 거의 없어 방식효과가 우수하였고, 블리스터 발생도 거의 없어 가장 우수한 배율로 분석되었다. 결론: 본 연구를 통해 그 성능이 인정된 수분 경화형 방식 코팅액에 대해 향후 새로운 성분 배율 실험을 통한 기능 향상과 시행 확대를 위한 제도적 개선 노력이 필요하다.
